SUPPORTING STRIP FOR CONIGAL LINER, PLATES IN THE BQVIL OF CENTRIFUGAL SEFABJATORS. i

Application filed ma as,

Be it known that I, Hans OLor Linneimn, engineer, subject of the King oi Swedeiu residing at 8 Fleminggatan, Stockholm,

Sweden have invented certain new and use ful lin )rovements 111 Sn 3 DOLtlllQ Stl'l as for Conical Liner Plates in the Bowl of Centrifugal Separators, oi which the following is a specification. i

In large bowls 01" centrifugal separators having conical liner plates it will not be sufficient to guide the latter at the. center, it being necessary to support the sainealso at the outer periphery. Since solid particles almost without exception are separated. from the treated liquid and by the influence oi the centrifugal force are forced, towards the Wall of the bowl, a space between the outer periphery of the liner and the wall of the bowl has to be provided for he said solid particles, on account whereof the liner cannot bear immediately against the wall of the bowl. To this purpose strips projecting from said wall are provided. Since the annular space at the periphery of the bowl unoccupied by the liner--the mud cha1nberis divided by said strips :nto

- :1 number of partitions separated. from one another, the use ol such strips has hitherto been connected with certain inconveniences described below.- It being impossible to supply the liquid to the liner in such a manner that the solid particles are collected uniformly in the mud chamber along the periphery of the liner plates the quantity of mud accumulated in diiterent partitions may. vary considerably. This will cause an increased pressure in the bearings upon the rotation of the bowl resulting'in an in- Spccification of Letters Patent.

-This invention the obj act that is to say the irregular deposit of the mud COYlSlS'tSlil that the strips are provided with one or more grooves preferably extending from the surtace bearing against the" and C the supporting strips provided with grooves D. With reference to the strength the supporting strips are provided with sup porting projections YE, which however, in case ot strips oi? less length may be omitted.

Nh at if claim as new and desire to secure by Letters Patent of the United 1. Bowls oi? centrifugal senatrators having conical liner plates and supporting: strips provided at the wall of the bowl, characterized by the strips being provided with grooves adapted to allow equalizing oi the deposit of mud in the annular space between the liner and the wall of the bowl:
